紅外線輻射約為普通焊條電弧焊的1～，氬弧焊電弧產(chǎn)生的紫外線輻射約為焊條電弧焊的5～20倍。在有限空間內(nèi)焊接時(shí)，臭氧的濃度可增大到危險(xiǎn)程度，在焊接過(guò)程中，還會(huì)產(chǎn)生二氧化碳，一氧化碳等有害氣體和金屬粉塵，這些都對(duì)焊工產(chǎn)生一定的危害。所以我們?cè)诤附舆^(guò)程中要做好防護(hù)，選用電極的材料，要盡量選用放射性小的鈰鎢。磨削電極時(shí)，要戴好口罩，手套，且工作后要洗手，讓危害降到比較低。高頻電磁場(chǎng)的危害焊接通常使用高頻振蕩器的頻率為200～500kHz，電壓2500～3500V，電場(chǎng)強(qiáng)度140～190V/m。引弧時(shí)，產(chǎn)生的高頻電磁場(chǎng)強(qiáng)度在60～110V/m之間，超過(guò)參考衛(wèi)生標(biāo)準(zhǔn)(20V/m)數(shù)倍，昆山RD12M焊絲工廠。在非熔化極氬弧焊和等離子弧焊割時(shí)，昆山RD12M焊絲工廠，常用高頻振蕩器來(lái)激發(fā)引弧，有的交流氬弧焊機(jī)還用高頻振蕩器來(lái)穩(wěn)定電弧。人體在高頻電磁場(chǎng)作用下，能吸收一定的輻射能量，產(chǎn)生生物學(xué)效應(yīng)，主要是熱作用。高頻電磁場(chǎng)強(qiáng)度受許多因素影響，如距離，振蕩器和振蕩回路越近場(chǎng)強(qiáng)越高，反之則越低。此外，與高頻部分的屏蔽程度等有關(guān)。人體在高頻電磁場(chǎng)作用下會(huì)產(chǎn)生生物學(xué)效應(yīng)，焊工長(zhǎng)期接觸高頻電磁場(chǎng)能引起植物神經(jīng)功能紊亂和神經(jīng)衰弱。表現(xiàn)為全身不適、頭昏***、疲乏、食欲不振、失，昆山RD12M焊絲工廠.眠及血壓偏低等癥狀。焊絲主要用于二氧化碳?xì)怏w保護(hù)焊、埋弧焊和電渣焊。昆山RD12M焊絲工廠</p><div

電感線圈的感抗電壓降使電焊機(jī)獲得較低的工作電壓，這是電焊機(jī)具有陡降外特性的原因。引弧時(shí)，電焊機(jī)能供給較高的電壓和較小的電流，當(dāng)電弧穩(wěn)定燃燒時(shí)，電流增大，而電壓急劇降低；當(dāng)焊條與工件短路時(shí)，也限制了短路電流。焊接電流調(diào)節(jié)分為粗調(diào)、細(xì)調(diào)兩檔。電流的細(xì)調(diào)靠移動(dòng)鐵芯4改變變壓器的漏磁來(lái)實(shí)現(xiàn)。向外移動(dòng)鐵芯，磁阻增大，漏磁減小，則電流增大，反之，則電流減少。電流的粗調(diào)靠改變次級(jí)繞組的匝數(shù)來(lái)實(shí)現(xiàn)。該電弧焊機(jī)的工作條件為應(yīng)在海拔不超過(guò)1000m，周圍空氣溫度不超過(guò)+40℃、空氣相對(duì)濕度不超過(guò)85％等條件下使用，不應(yīng)在有害工業(yè)氣體、水蒸汽、易燃、多灰塵的場(chǎng)合下工作。二、直流弧焊機(jī)(一)結(jié)構(gòu)由于整流或直流弧焊機(jī)與直流弧焊發(fā)電機(jī)比較，因沒(méi)有機(jī)械旋轉(zhuǎn)部分，具有噪音小，空載損耗小、效率高、成本低和制造維護(hù)簡(jiǎn)單等優(yōu)點(diǎn)。因此，有取代直流弧焊發(fā)電機(jī)的趨勢(shì)，在這里只介紹整流式直流弧焊機(jī)。整流式直流弧焊機(jī)常用型號(hào)如ZXG—300、ZXG—400等。硅整流電弧焊機(jī)是利用硅半導(dǎo)體整流元件(二極管)將交流電變?yōu)橹绷麟娮鳛楹附与娫?。圖3—10為硅整流電弧焊機(jī)的結(jié)構(gòu)示意圖。浙江焊絲工廠主要用于工件表面的手工堆焊，以滿足如抗氧化、耐磨損和高溫下耐腐蝕等特殊性能要求。</p><div

按適用范圍不同，可分為斜三角形和正三角形兩種運(yùn)條方法。其中斜三角形運(yùn)條法適用于焊接T形接頭的仰焊縫和有坡口的橫焊縫。其特點(diǎn)是能夠通過(guò)焊條的擺動(dòng)控制熔化金屬，促使焊縫成形良好。正三角形運(yùn)條法*適用于開坡口的對(duì)接接頭和T形接頭的立焊。其特點(diǎn)是一次能焊出較厚的焊縫斷面，有利于提高生產(chǎn)率，而且焊縫不易產(chǎn)生夾渣等缺點(diǎn)。三角形運(yùn)條法6)圓圈形運(yùn)條法。如圖3—22所示，將焊條末端連續(xù)作圓圈運(yùn)動(dòng)，并不斷前進(jìn)。這種運(yùn)條方法又分正圓圈和斜圓圈兩種。正圓圈運(yùn)條法只適于焊接較厚工件的平焊縫，其優(yōu)點(diǎn)是能使熔化金屬有足夠高的溫度，有利于氣體從熔池中逸出，可防止焊縫產(chǎn)生氣孔。斜圓圈運(yùn)條法適用于T形接頭的橫焊(平角焊)和仰焊以及對(duì)接接頭的橫焊縫，其特點(diǎn)是可控制熔化金屬不受重力影響，能防止金屬液體下淌，有助于焊縫成形。圓圈形運(yùn)條法(三)收尾電弧中斷和焊接結(jié)束時(shí)，應(yīng)把收尾處的弧坑填滿。若收尾時(shí)立即拉斷電弧，則會(huì)形成比焊件表面低的弧坑。在弧坑處常出現(xiàn)疏松、裂紋、氣孔、夾渣等現(xiàn)象，因此焊縫完成時(shí)的收尾動(dòng)作不*是熄滅電弧，而且要填滿弧坑。收尾動(dòng)作有以下幾種：(1)劃圈收尾法。焊條移至焊縫終點(diǎn)時(shí)，作圓圈運(yùn)動(dòng)，直到填滿弧坑再拉斷電弧。打開焊絲包裝應(yīng)盡快將其全部用完（要求在一周以內(nèi)），一旦焊絲直接暴露在空氣中，其防銹時(shí)間將**縮短。蘇州激光焊絲供應(yīng)商</p><p
